On your site plan there is often a notation that the floor level can vary by 100mm either way so if yours is within that tolerance then it is fine as it has been laid. Is there any reason that having your slab 100mm lower could be problematic?

Is there any reason that having your slab 100mm lower could be problematic? Can’t see anything on drawings regarding a tolerance level. I’m not sure, I was just thinking FFL has been set for a reason (architect design and/or council?) and now not at that level. Slab is still above NGL but not by much. Water getting into the house was my first thought if thats a potential flow on effect on being lower? There are pipes that are on same level with our outdoor slab (set down lower than house slab) but if that’s the only issue hopefully they can be lowered Re: Slab low 4Jun 06, 2023 9:47 pm Ask to see your enginnered drainage plan Foremost Building Expert in Australia,assisting with building problems/disputes, building stage inspections,pre-contract review advice for peace of mind 200 blogs http://www.buildingexpert.net.au/blog If you can calculate the reasonable charged head from let's say 100mm below the gutter to the top of where the vertical riser's horizontal discharge pipe will be, that… 11 17592 Those span tables can be pushed a little for a low deck if you dont mind a little flex.
